Description

CouchDB currently replicates attachments by inlining them in the JSON representation of the document. This puts a load on the DB in the case of large attachments. It might be possible to avoid inlining attachments by

a) adding a

{new_edits, false}

equivalent option in the standalone attachment API, or

b) accepting a multipart format that would allow JSON docs and binary attachments to be transmitted in one shot, or

c) something I haven't thought of yet
